ICE BOX FOR REFRIGERATORS.

Application filed July 8, 1922. Serial No. 573,563.

.T all whom it may concern Be it known that l, EMIL onn'rn, a resident of Hamilton Beach, Queens County, N. Y., and a citizen of the United States, have invented certain new and useful Improvements in Ice Boxes for Refrigerators,

of which the following is a specification.

This invention relates to refrigeration and more especially devices to be used in connection with the preservation of organic material and the cooling or freezing of materials used as food or beverage and its object is to provide an ice box or hollow shell of the size and shape of the interior of a box, tub or other structure and into which may be introduced crushedice and sodiumchloride or similar salt'so that the ice and salt coming in contact with each other will produce a lower temperature than when ice alone is used as a refrigerant and cool the adjacent air or liquid.

These and other objects and details of the invention are more fully described in the following specification, set forth in the apillustrated in the accompanying drawings, wherein,

Figure 1 is a top plan view of an ordinary refrigerator partly in section.

Fig. 2 is a horizontal sectional view through the same refrigerator.

Fig. 3 is a front elevation of the same and partly in section.

Fig. 4: is a perspective view, partly broken away, of the device removed from the re frigerator casing.

Fig. 5 shows the application of the device to a railway car.

Fig. 6 shows a water cooler constructed in accordance with the invention.

Fig. 7 shows it applied to an ice cream freezer.

Fig. 8 shows its adaptation to a corpse cooler.

The device comprises an ice box independent of the casing of the enclosure it is intended to cool and closely fitting the inner walls of the enclosure but capable of ready removal and return if repairs are necessary. A serious objection to the ordinary refrigerator is its tendency to rust at some point and leak and become worthless. With this device the more valuable part of a refrigerator, the frame and casing, is always protected but the ice box itself may be instantly removed and its damaged part made accessi ble.

In the various views of the drawings the ice box 10 is of sheet metal and as shown in Figs. 1, 2, 3, and a is adapted to be located within the casing 11 whose door 12 is of such dimensions as to permit of the ready removal of the said box, which consists of the parallel walls 13 and bottom 14 andis a substantially U-shaped structure mounted on I its ends.

Vertical channels 15 are arranged between the walls either by means of the partitions shown or by pipes 16 extending nearly to the bottom of the box, as shown in Fig. 3, and both the channels and the pipes are perforated. They are adapted to contain the salt to make a freezing mixture for the ice box when it is desired to cool the refrigerator and as the two vertical containers 15 and 16 are open at the top and closed at the bottom they will feed the salt to the melted waters from the ice. Cleats 17 for a shelf are also shown on the inside of the box.

The ice is supplied to the box from a shelf 1'? at its top and it will be observed that the outer edge of the ice box and the salt passages are higher than the inner wall and this is to allow the ice to beswept from the said shelf into the box and not over its sides to dampen the interior of the casing. The

casing 11 is filled with the usual insulating filling of sawdust, charcoal or similar material.

The ice box is filled with crushed ice from the shelf 17 and as it melts a brine is formed by the salt and the ice preserved in its congealed form for a considerable time, but in case that more ice is desired the water may be drawn off by means of the cook 18 that is independent of the refrigerator and passes through a perforation therein to be screwed into a suitable bushing 19 in the ice box.

A railway freight car adapted to carry perishable material may be constructed as shown in Fig. 5 and the ice box arranged around its inner sides. The left hand box is shown divided at 10' to facilitate its removal from the car, and the usual salt receptacles l5 and 16 are provided. Outlets 21 are shown to drain the box beneath the car.

The water cooler shown in Fig. 6 has a cylindrical ice box 22 with open top and a shelf 23 to aid in the filling of the same. Salt passages24l also depend into the annular chamber and are suitably suspended. In this instance it may not be necessary to prolocated in the cooler case 27.

vide a drain cock and the boX may be removed from the cooler andits contents poured out. In an ice cream freezer the ice boX 22 is also annular in shape and loosely fits the bucket 25 but in this instance has no filling shelf as care is not necessary in filling the box. To remove the surplus' water, however, a siphon 26 may be used and the same means adopted for the watercooler above described. L Y

A further application of this device is shown in Fig. 8 and illustrates a corpse cooler and showing the U-shaped device 10 In this instance the salt receptacles 28 are located in the upright walls while in the outer bottom wall may be a drain pipe 29.

It is obvious that a device of this nature may be used in other waysand with other modifications and arrangementswithout departing from the essential features above described or from the scope of the following claims.

As shown in Fig. 2 and in dottedlines in Fig.3,floats of wood or cork 30 may be placed in the spaces between the salt pipes to support the ice and lieep it as far as possible above the water and at the same time to more effectually cool the air in the upper part of the box or where there is a I tendency for the warmer air to collect.

What I claim as newis: 1. In an ice box for refrigerators, the COIIIbllltLtlOll'Of a shell comprising inner and outer walls with aspace for ice between them and a bottom wall, perforatedpartitions in the space between the walls and forming compartments to contain salt to impregnate the lower water and ice, and a drain for said shell. Y

2. In an ice box for refrigerators, the combination of a shell adapted to be inserted in a casing and comprising inner and outer walls closed at the bottom and having ashelf within the inner walls at the top a drain for the shell, and vertical partitions between the walls with perforations at their lower ends to form passagesto introduce salt to the water and the ice;

3. In an ice box for refrigerators, the

combination of a shell comprising inner and outer walls and adapted to be fitted in a casing, a drain at the bottom of the shell, a shelf unitingthe inner walls at the top, and receptacles for salt comprising vertical perforated pipes located in-the space between the walls and adapted to afford a means whereby the water may dissolve the salt at the lower end of the shell.

In testimonywhereof I hereunto affix my signature.

EMIL wonarn.
